HORIZONTAL BARREL-TRUSSING MACHINE.

Specification of Letters Patent.

Patented Dee. 15, 1908.

Application filed May 25, 1905. Serial No. 262,186.

To all 'whom 'it may concern:

Be it known that I, EDWIN F. BEUGLER, of Buffalo, in the county of Erievand State of New York, a citizen of the United States, have inventedcertain new and useful Imrovements in Horizontal Barrel-Trussing lachines, of which the following is a specification.

This invention relates to va machine for driving heavy truss hoops onunheaded bar rel bodies preparatory to cutting the croze in each endthereof and heading up the barrels.

The barrels for which this machine is chiefly designed is that known inthe trade as tight barrels or barrels used for holding liquids, such ascider, vinegar, etc., andwhich have to be made very tight to preventleaking of the liquid.

ln this machine the rough barrel bodies composed of staves andpreliminary hoops for holding the staves together are placed for thepurpose of having heavy metal hoops, known as truss hoops, driven firmlythereon.

One of the features of the invention consists in two or more screwthreaded rods between which the trussing or hoop driving mechanism islocated, said screw threaded rods being connected to said trussingmechanism to reciprocateA the same and being rotated at uniform speed sothat the trussing mechanism is always moved in perfect alinement and thestrain of the trussing pressure borne at two or more separated points.

Another feature consists in corrugating or serrating the annular surfaceof that portion of. one of the trussing rings which comes in contactwith the stave ends for the purpose of relieving the dead crushingpressure against the stave ends and thus preventing the splitting orchecking of the staves or the crushing of the stave ends.

The invention also relates to certain other features and improvementsand to certain novel details of construction, all of Which will be fullyand clearly hereinafter described and claimed, reference being had tothe accompanying drawings, in which,-

Figure 1 is a side elevation of the machine. i Fig. 2 is a centrallongitudinal section 'i through the machine.

Fn referring to the drawings for the details of construction, likenumerals designate like parts.

The frame of the machine consists of two end members 1, twolongitudinally extending bars or rails 2, the ends of which are seatedand securely fastened in the end members 1, so as to rigidly connectsaid end members and a longitudinally extending tie-rod 3, the ends ofwhich are screw threaded and passed through openings in lugs 4,extending vertically from the top of the end frame members, the tie-rodbeing securely fastened in place by opposed nuts which are secured uponthe rod on each side of the lugs 4, see Figs. 1 to 6, inclusive. Thisconstruction gives a comparatively light, and an exceedingly rigid andsimple frame, the longitudinal rails 2, serving the double purpose offrame members and of slideways upon which the truss hoop drivingmechanism is supported and slides.

The driving heads are moved toward or from each other by twolongitudinally extending parallel horizontal screw threaded shafts, theupper shaft 5, being mounted in bearings 6, which are formed in theupper ends of the end frame members, and the lower shaft 7, beingmounted in bearings 8, in

the end frame members and vertically beneath the upper shaft 5. Theseshafts are each provided with a left hand and a right hand thread, theleft hand thread being formed on the left half of each shaft and for thegreater portion of said half; and the right hand thread being formed onthe right half of each shaft and 'for the greater portion of said half,see Fig. 2. The shafts 5 and 7, are connected so as to rotate at thesame speed, the motion being transmitted from the lower shaft 7, to theupper shaft 5, by a set of gears as shown in Figs. 3, 5 and 6. The lowershaft 7, is slightly longer than the upper shaft 5, and has its endsslightly reduced and projecting beyond the end frame members, see Fig.2. Two pulleys 9 and 10, are mounted upon the shaft 7, one at each endthereof and rotate oppositely to each other. The pulleys are mountedloosely upon the shaft and rotate independently thereof. Two

friction clutches 11 and 12, are secured to the shaft 7, by set screwsthe friction clutch 11, being placed upon the shaft in proximity to thepulley 9, and the friction clutch 12, being placed upon the shaft inproximity to the pulley 10, see Fig. 2. The pulleys are brought intoengagement with the friction clutches by means of a longitudinallyextending sliding bar or shaft 13, which is mounted in bearings 14,formed in the end frame members and vertically beneath the shafts 5 and7. A. collar 15, is rigidly secured by set screws to each end of the bar13, each collar having an upwardly extending portion which looselyencircles the reduced inwardly extending portion of the adjacent pulleyhub, see Fig. 6. A collar 16, is secured by a set screw to the end ofthe reduced portion of each pulley hub so as to prevent any longitudinalmovement of the collar 15, upon said hub. A truss rod 17, extendslongitudinally beneath the sliding bar 13, and has its ends passedthrough depending portions on the collars 15. The ends of the rod arescrew threaded and are locked to the collars 15, by opposed nuts asshown in Fig. 6. This truss rod prevents any buckling of the sliding bar13, while it is being shifted to bring the pulleys into engagement withthe friction clutches. The bar 13, is shifted by means of an angularlever, the horizontal portion 18, of which is mounted in bearings 19,extending from one of the end frame members 1, and passes transverselybeneath the sliding bar 13. The outer portion 20, of the angular leverbends at right angles to the portion 18, and extends diagonally upwardinto convenient reach of the operator, see Figs. 3 and 5. A collar 21,having an upwardly extending iingeror lug 22, is secured to the portion18, of the angular lever, and a collar 23, having a laterally extendinglug 24, is secured to the sliding bar 13, directly above the horizontalportion of the angular lever. The lateral lug 24, has a vertical o eningformed therein in which the finger or ug 22, loosely fits. It will beseen that a rocking movement of the angular lever will transmit alongitudinal movement to the sliding bar 13, and so bring either of thepulleys into engagement with its adjacent friction clutch at the will ofthe operator. The collar 21, is also provided with a laterally extendinglug 25, through which the lower end of a comparatively long bolt 26, ispassed, the upper end of which is seated in a portion of the adjacentend frame member. Two spiral springs 27, encircle the bolt 26, one oneach side of the lug 25, and serve to maintain. the angular lever in anormally central position and the pulleys normally disengaged vfrom thefriction clutches, see Fig. 3.

The screw threaded shafts 5 and 7, are connected so as to rotate inunison by a set of gears, as before noted. These gears are shown inFigs. 1, 2, 3, 5 and 6, to which figures reference will be had in thescription.

A ring 28, having a lateral flange 29, extending outwardly from one sidethereof is secured to one of the end frame members by bolts 30, whichpass through the flange 29. The ring 28, is secured to the end fram-emembers exactly between the ends of the shafts 5 and 7. in the preferredadaptation of the invention as illustrated in the accompanying drawings,the ring is secured to the left hand end. member of the machine frame,see Fig. 6. A gear wheel 31, is mounted upon the ring 28, the ringserving as a hub upon which the gear revolves. The gear wheel 31, mesheswith two pinions 32 and 33, one of the pinions being mounted upon eachof the shafts 5 and 7. By this construction, both the shafts 5 and 7,are driven in the same direction and at a uniform speed. A gear casingor guard 34, is secured to the ring 28, by bolts 35, which pass throughlugs extending from the casing or guard 34, and form the inside of thering and also serves to hold. the gear wheel 31, in place upon the ring28, see Fig. 6. The ring 28, is provided with a number of pockets 36,which are filled with oil soaked waste so as to lubricate the peripheryof the ring upon which the gear revolves.

There are two sets of hoop driving mech anisms, each set of which drivesthe hoops upon one end of the barrel. The two s'ets are placed. so as tooppose each other and are moved. toward or from each other by therotation of the screw threaded shafts 5. and 7. As each set of drivingmechanism is practically a duplicate of the other, a detaileddescription of but one set will be given, the reference numerals on thedrawings, however, being placed. upon like parts of each set. A detailedand separate description of the minor points in which the two setsdiffer will be hereinafter given.

In the following description of the hoop driving mechanism attentionparticularly called to Figs. l and 2, and to Figs. 7 to l16, inclusive.Each set of driving mechanism comprises a driving head, a plurality ofdriving arms pivotally secured to the driving head and. a plurality ofdrivers secured to the ends of the driving arms and to the driving headto force the truss hoops upon the barrel. The driving head 37, ispreferably circular in shape and hollow in construction and is provided.with a centrally projecting hub 38, the outer portion of which isslightly reduced. in diameter. The driving head is slidably supportedfrom the rails 2, by two sleeves 39, which are cast integral with thedriving head and are connected thereto by ribs or webs as shown in Figs.l, 4, 5 and 7. Two split nuts which engage with the screw following de-Y threads on the shafts 5 and 7, are secured to the driving head; thenut 40, which engages with the thread on the upper shaft 5, having fromeach other as shown in Fig. 4.

laterally extending lugs 41, through which bolts are passed to securethe nut to vertically extending lugs 42, on the driving head, see Fig.5. The nut 43, which engages with the thread on the lower shaft 7, issecured to the web connecting the driving head and the sleeves 39, bybolts which pass through laterally extending lugs 44, on the nut 43,Aand through the web, see Fig. 7. The two halves of each of the nuts 4l)and 43, are fastened together' by bolts 45, as shown in Fig. 7.

The driving head 37, is provided with two sets of drivers, the setwhich. drives the end hoop upon the barrel being adj us tably secureddirectly upon the face of the driving head as shown in Fig. 9, and theset which drives the bilge hoop being secured to the outer ends ofradially extending driving arms as shown in Fig. 8. rlhe end hoopdrivers which are preferably six in number, are formed as shown in Figs.5, 6, 9, 13, 14, 15 and 16, and are secured to the face of the drivinghead and equi-distant from the center thereof and Each. driver issecured in place by a bolt 46, the head of which seats 1n. a radiallyextending T slot 47, formed in the face of the driving head. Each driveris composed. of a rectangular shaped block 48, a driving plate 49, ofhardened metal, and a guide block 50, the whole being fastened. togetherand to the driving head by the bolt 46, which passes through openings.in the block 48, and in the plate 49, and through a slot block 50. Anut is screwed upon the outer end of the bolt to fasten the driverfirmly to the driving head, see Fig. 9. The rectangular shaped block 48,has a rib extending from the face adjacent to the driving head which ribfits into the narrow portion of the T slot and prevents any pivotalmovement of the driver upon the bolt. The guide block 5i), provided withtwo lugs 5], which straddle the plate 49, and the block 48, and preventsthe block 50, from rotating on the bolt 46. A set screw is screwed.through one of the lugs 51, to additionally secure the block in place.Two lugs 52, extend from the block 50, oppositely to the lugs 51, andhave bev eled edges which guide the hoop so that it is evenly gripped bythe driving plates 49. Each driver maybe adjusted upon the face of thedriving head by loosening the nut upon the outer end of the bolt 46, andmoving the driver toward or from the center of the driving head. Thedrivers for driving the bilge lhoops are shown in Figs. l, 2, 4, 7, 8,1l), 1].

and 12.

A plurality of driving arms 53, are pivoted. by pins to lugs 54,extending from the driving head and pass through radially extendingslots which are formed. in the driving head, see Fig. 7. The outer endsof the driving arms are connected by angular arms or con- .in the guidenecting links 55, to a shiftable collar 56, which is supported by thereduced portion of the hub 38, of the driving head. The links 55, aresecured to the driving arms by pins which project through the slots inthe outer ends of said links and are pivoted to the shiftable collar bypins 57, which extend from said collar. A collar 58, is fastened by aset screw to the outer ends of the reduced portion of the hub 38, andprevents any longitudinal movement of the shiftable collar 56, on saidhub and also serves to secure the inner ends of the connecting links 55,in place upon the pins 57.

The drivers 59, are formed as shown in Figs. 8, 11 and 12, having asocket in which the end of the driving arm is fitted. The other end ofthe driver has a square flange which grips the truss hoop and drives itinto place. The socket is in the form of a Roman cross, so that if oneedge of the fiange should become damaged, the driver can be removed fromthe driving arm and given a quarter turn to bring a new edge of theflange into use to drive the hoop. By making the socket cruciform thedriver plate may be locked positively, unrotatably and immovably in anyone of four positions to which it may be adjusted to the driver arm. Theadvantage of this construction is that approximately four times the wearis obtained over a driver having but one edge. It is not howevernecessary to make the socket cruciform although that shape is thoughtpreferable as any form having corners of identical conformation andequal in number to the gripping and driving edges of the flange may beused; the purpose being to enable any one of the edges to be arranged inoperative osition and to lock the driver in any one of t e positions towhich it may be turned. The driver is securelyl fastened to the end ofthe driving arm by a set screw as shown in Fig. 8. The driving arms 53,are moved toward and from the barrel by means of a rock shaft which maybe operated automatically or by the foot of the operator, see Figs. 1, 5and 7. A square rock shaft 60, has its ends journaled in the end framemembers 1, and a crank 61, is mounted upon the shaft so as to slidethereon. This crank is connected by means of a connecting rod 62, to acrank arm 63, extending from the shiftable collar 56, and formedintegral therewith. Two blocks 64, are fastened to the rock shaft 60,and a foot lever 65, has its ends bent at right angles and seated indepressions which are formed in the blocks 64, see Figs. 5 and 80. Aplate which has a foot treadle 66, formed thereon is bolted to the footlever so that the trcadle is within convenient reach of the operator.

It will be seen by the above description and by referring to thedrawings that a downward movement of the foot lever will cause the shaft60, to rock and give an upward movement to the crank v61. This causes apartial rotation of the shiftable collar 56, by means of the rod 62, andmoves the drivers 59, toward the barrel by spreading the outer end ofthe driving arms 53, by means of the connecting links 55. The driversare returned to their normal position by means of a crank 67, which issecured to the rock shaft 60, near one end and a spring 68, which hasone end secured to the crank 67, and the other end to a lug extendingfrom the adjacent end frame member, see Fig. 24.

The automatic means for operating the drivers is illustrated in Figs. 1,5, 28, 29 and 30.

One of the sleeves 39, of the driving head which is adjacent to the footlever 65, has a lug cast integnl therewith which has a vertical openingformed therein. A bar 69, has one end rigidly secured in this opening byset screws and has a trigger 70, pivoted at its other end by a pin. Thistrigger is pivoted so as to have a swinging movement in one direction,but is locked against any movement in the opposite direction. The plateon which the foot treadle 66, is formed has an inclined portion 71,against which the bottom edge of the trigger is adapted to operate. Itwill be seen that when the driving heads are moved toward the barrel,the trigger strikes the inclined portion of the plate and depresses thefoot lever and rocks the shaft i65, in the same manner as the operatorsoot.

Mechanism is provided for leveling the barrel before the truss hoops aredriven into place and is illustrated in Figs. 1, 2, 3, 5, and 6, andFigs. 17 to 23, inclusive. This mechanism is in two sets, a set beinglaced at each end of the machine and as eac i set is a duplicate of theother, but one se't will be described. The reference numerals on thedrawings will be placed upon like parts of each set. y

The hub 38, of the driving head 37 ,has an opening formed therein inwhich a longitudinally extending sliding shaft 72, is supported.

The outer end of the shaft 7 2, passes loosely through an opening 73,see Fig. 18, in a slide block 74, which is slidably mounted in a slideway 75. This slideway 75, is secured by bolts to a transverselyextending portion of the end frame members 1. The slide block 74, isprovided. with vertical and horizontal flanges 76 and 77, which havefiat faces as shown in Figs. 1.7 and 18.

A transversely extending rock shaft 78, is journaled in bearings in theend frame members 1, above the slideway 75, and a hub which is providedwith two crank arms 79, is securely fastened. to the middle of the rockshaft, see Fig. The ends of the crank arms 79, are provided with rollers80, which l weighted crank arm 81, is keyed to each end of the shaft.Each crank arm is connected by a chain to the upper end of a powerfulspiral spring 82, the lower end of which is secured by an eye bolt to alug extending from the end frame members 1. Each crank arm 81, has aprojection 83, which strikes against a lug 84, see Fig. 1, on the endframe members and limits the outward movement of the crank arm.

A leveling ring 85, is secured to the inner end of each of the shafts72, each ring having one of its edges beveled as at 86, in Fig. 31, anda series of webs 87, which connect the ring 85, to a central hub 88, seeFig. 4. Each ring also has a series of short webs 89, the webs 87 and89, extending beyond the beveled edge of the ring and having their outerends rounded as shown in Figs. 1, 2, 6 and 31. The rounded edges of thewebs and the beveled edge of the ring guide the ring into the open endof the barrel. One of the leveling rings 85, has a peripheral flange 90,see Fig. 6, against which the edges of thefstaves fit so as to make themperfectly level and flush with each other. This iange 90, has a numberof radial projections 91, which prevent the end hoop from sliding offthe barrel before it is driven into place.

It has been found in practice that the barrel staves are not always ofequal length therefore were either crushed or bulged out at the middle,or were not leveled exactly by the flange 90, as it could not touch theedges of both the long and the short staves. To remedy this, the flange90, is omitted onone of the leveling rings 85, and a ring 92, having aseries of V sha )ed peripheral teeth 93, is substituted there or, beingfastened in place by bolts as shown in Figs. 4 and 31. The lateral edge94, of each tooth 93, is brought to a shar edge and is beveled so thatthe peripheral3 edge of the tooth is shorter than its base, see Figs. 31and 32.

It will be seen by the above description and the drawings that when theleveling rings 85, are forced into the open ends of a barrel, the edgesof the longer staves will strike against the flange 90, on one ring. Thebeveled edges 94, of the teeth will enter the longer staves until theedges of the shorter staves are reached and all the staves pushed evenlyagainst the flange 90. The

purpose of beveling the edges 94, of the teeth is so that the deepestcut in the edges of the staves will be on the inner surface so that whenthe croze is cut and the uneven edge of the barrel trimmed off, theedges of the staves will not be mutilated.. The beveled edge of theteeth serve also to force the staves outward against the hoo s.

A portion of the sliding shaft 72, is screw threaded and two splitcollars 95, having screw threaded openings are mountedu on this portion.of the shaft being locked in p ace by transverse bolts as shown in Figs.20 and 21. shaft, the distance between the two leveling rings 85, can bevaried to provide for barrels of different lengths.

When a barrel is placed in position to be trussed and the driving headsmoved toward each other, the tension of the springs 82, acting upon thecranks 81, rock shafts 78, cranks 79, and slide blocks 74, forces 'theleveling rings 85, into the open ends of the barrel until the edges ofthe staves strike the peri heral flange 90, which levels one end of thearrel and brings the barrel into a perfectly circular form. The trusshoops are now driven tightly into place and as the driving heads recedefrom the barrel, they carry with them the shafts 72, by reason of thehubs 38, striking against two of the collars 95, see Figs. 5 and 6.

Barrel supports are adjustably secured to the side members or rails 2,to support the barrel in a central position in the machine, see Figs. 1,2 and 4. The supports consist of angular bars 96, which are adjustablysupported in blocks 97, secured to the rails 2, by U bolts. The bars 96,are fastened in the blocks 97, by set screws and may be adjusted inlength to support barrels of different diameters.

A device for automatically removing the barrel from the machine isprovided and is illustrated in Figs. 1, 2, 4, 25, and 26. A square rockshaft 98, has one end supported in a bearing in one of the end framemembers 1, and its other end supported in a bearing 99, secured to anddepending from one of the side rails 2, see Fig. 27. A collar 100, issecured to the shaft 98, at about the middle of the machine and has anextension 101, formed integral therewith. This extension has adepression formed in its top surface in which one end of a bent bar 102,is seated being held in lace by a long bolt 103, which is encircled y aspiral spring 104. The shaft is rocked to eject the barrel by a roller105,. which is mounted on a pin at the lower end of a bar 106. The baris secured in an o ening in a lug 107 ,j extending from one o thesleeves 39. The roller 105, operates against the inclined surface 108,of a Weighted swinging arm or trigger 109, which is pivoted to adiagonally extending crank arm 110, secured to the shaft 98, see Fig.25. A stop 111, on the crank 110, prevents the movement of the vtriggerin one direction so that the crank is depressed by the roller cominginto contact with the inclined surface 108, of the trigger 109, whenmoving in one direction, see Fig. 26, and thus rocks the shaft to ejectthe barrel.

The operation of the machine Will readily be understood from theforegoing description and the drawings.
